UNITED STATES PATENT onnron JOHN E. CI-IALMAN, OF CHICAGO, ILLINOIS, ASSIG-NOR '10 UNION SPECIAL MACHINE COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

BINDER FOR SEWING-MACHINES.

Specification of Letters Patent.

Application filed October 7, 1916. Serial No. 124,375.

To all whom it may concern:

Be it known that I, JOHN E. Grumman, a citizen of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Binders for Sewing- Machines, of which the following is a description, reference being had to the accompanying drawing, and to the figures of reference marked thereon.

The invention relates to new and useful improvements in binders for seWin machines and more particularly to a' inder which is adjustable for binding strips of diiferent widths.

An object of the invention is to provide a binder which will besimple in construction and readily adjustable for varying the capacity of the binder for different widths of binding strips.

A further object of the invention is to provide a binder of the above character having a body portion provided with inturned edges forming a guiding recess for the binding stri and an adjustable member located within the guiding recess, together with means for shifting this adjustable member toward and from the inturned edges of the binder so as to vary the ca acity of the binder for different widths 0 binding strips. I

These and other objects will in part be obvious and will in part be hereinafter more fully disclosed. a a

In the drawings, which show by way of illustration, one embodiment of the invention:-

Figure l is a perspective view of a binder having my improvement applied thereto;

Fig. 2 is a longitudinal sectional view through the binder;

Fig. 3 is a sectional of Fig. 2;

Fig. 4t is a rear side elevation of the binder;

Fig. 5 is an end view of the receiving end of the binder; and

Fig. 6 shows a strip of material having a binding strip applied thereto by my 1mproved binder.

The binder embodying my invention is particularly adapted for guiding a relatively narrow binding strip and applying the same to a shoe tongue or similar article although,

view on the line 3-8 of course, the binder may be used for other purposes.

The binder consists of an outer body portion having its upper and lower faces substantially parallel at the delivery end thereof' and the edges thereof turned in between the receiving and delivery ends of the binder so as to take a binding strip which is substantially straight and fold the same between its edges as it is delivered to the stitching mechanism. Located in this guiding recess for the binding strip is a curved guiding member forming the rear inner wall of the binder and this guiding member adjacent the delivery end of the binder may be adjusted toward and from the inturned edges of the binder so that the U-shaped passage formed by the adjustable guiding wall and the body portion of the binder may be varied for different widths of binding strips. By this adjustment the binding strip may be fed so that the needle will penetrate the same adjacent the edge thereof and this position of the binding strip may be maintained for 1 that the longitudinal axis of the binder is substantially parallel with the line of feed. Thisfbinder is especially adapted forattaching a binding strip to a small article such as the tongue of a shoe.

In Fig. 6 of the drawlngs, I have shown a .shoe tongue indicated at'T, to which a binding strip S is attached by a line of stitches s.

The body portion of the binder is formed of a single integral structure. The upper and lower side walls 6 and 7 are gradually turned over from the receiving end of the binder where they are substantially vertical to the delivery end of the binder where they are substantially horizontal. The edges of these side walls are turned in at 8 and 9 respectively so that the binder at its receiving end has a substantially vertical guiding passage 10, while at its delivery end it has a substantially U-shaped guiding passage 11. Located within the guiding recess is a guiding member 12. This guiding member is formed integral with the rear wall of the I binder at the receiving end thereof and said guiding wall extends longitudinally of the binder the entire length thereof. This guiding member is curved to conform with the rear wall of the binder so that at the de livery end of the binder said uiding member 12 is substantially U-shape This guiding member 12 is a spring member and is so shaped as to normally rest against the rear wall of the binder. A screw 13' is threaded througlrthe rear wall of the binder and is adapted to press against the rear face of this guiding member 12 adjacent the delivery end of the binder. By turning this screw in one direction the guiding member is forced away from the rear wall of the binder and toward the inturned edges of the binder. W hen the screw is turned in the opposite direction the spring of the guiding member will hold it against the screw and this will causethe guiding member to be moved away from these inturned edges. When the binder is set as shown in Fig. 3, it will be apparent that a certain width binding strip will pass through the binder and its edges will be guided by the inturned side'edges of the binder. The binder is so constructed that its inturned edges form recesses, the ends of which are located in a line just within the line of stitching, so thatthe needle will penetrate the binding strip adjacent the edges thereof.

When a. narrower binding strip 'is to be stitched to an article, then the guiding 1nember 12 is adjusted. by turning the screw 13 so as to bring the guiding member closer to the inturned edges 8 and 9 and this reduces the capacity of the binder so that when the narrow binding strip passes through the binder, its edges will be held well out to the extreme outer parts of the guiding recesses formed by theinturned edges 8 and 9 and, therefore, the binding strip will be properly Copies of this patent may be obtained for five cents each,vby addressing the Commissioner directed to the stitching mechanism so that the needle will pass through the binding strip adjacent its edges.

It is obvious that minor changes in the details of construction and arrangement of parts may be made without departing from the spirit of the invention, as set forth in the appended claim.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

A. binder for sewing machines including in combination an outer body portion adapt ed'tobe attached to a sewing machine with its longitudinal axis substantially parallel with the line of feed, said body portion being bent to form a U-shaped guiding nien1- ber at its delivery end and having its side edges inturned, whereby a binding strip may be folded between its edges and the edges thereof guided by said inturned portions, an auxiliary guiding member located within said outer body portion and extending longi-- tudinally of the binder, said auxiliary guiding member being disposed so as to engage the outer face of the binding strip at the fold therein, the front end of the auxiliary guiding member being rigidly secured to the front end of the body portion and means located'adjacent the delivery end for adjusting said auxiliary guiding member toward and from said inturned edges of the outer body portion, for varying the capacity of the binder for different widths of binding strips and for maintaining the edges of the binding strip against the respective inturned edges of the body portion.

In testimony whereof, I affix my signature, in the presence of two witnesses.
